Abrams will boldly go where he's actually gone before. Which is why the stakes are even higher. The sequel to his wildly successful reboot of "star trek" now in theaters across the country.

Reporter: And much like the characters in his very personal mule vie "super 8." Lights and camera shoot on that end. J.J. Shooting on super 8 as a kid. I loved my grandfather.
